Filed: 1920-07-12
Abstract: 149,215. Huth Ges., Dr. E. F., and Rosenbaum, B. Aug. 28, 1917, [Convention date]. Wireless telegraphy and telephony.-In a combined transmitting and receiving arrangement for wireless telephony, a microphone and receiver, such as are used in ordinary line telephony, are connected in or coupled to a common circuit coupled to the transmitting and receiving apparatus, the microphone currents, or the received currents or both, being modified by amplifiers or the like to make them of the same order of magnitude, in the common circuit. In the arrangement shown in Fig. 1 received impulses are transmitted through the receiver 8 and amplifier 12 to the telephone. Microphone currents are amplified by the intermediate relay 11 before being impressed upon the transmitter 6. In a modification the microphone 9 is inductively coupled to the common circuit. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention may be adapted for telegraphy by substituting appropriate apparatus for the microphone 9 and telephone 10. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to the photomechanical correction of colours
IPC: G03F3/06
Filed: 1950-08-24
Abstract: 693,703. Photomechanical colour correction. THIELE, W. Aug. 24, 1950, No. 20978/50. Classes 98 (i) and 98 (ii). A colour correction method comprises photographing an object to produce a plurality of uncorrected separation transparencies placing a first of them in a first plane in a path of light from a first source, placing a photosensitive emulsion in a second plane and forming an image thereon with the aid of a lens, removing and processing the emulsion to form a mask, placing a second of the transparencies in the first plane in the same position as was occupied by the first of the transparencies and in contact with a second photo-sensitive emulsion with the latter remote from the lens, placing the mask in the second plane in the position as was occupied by the image of the first transparency, forming on the second emulsion with the aid of a second light source and the same lens an image of the mask which is in register with the second transparency image, and removing and processing the second emulsion to produce a colour-corrected separation record. The use of an optical separation image instead of an actual transparency in the first plane is included. An apparatus comprises a lens which has a light-tight structure on each side, means to support and to ensure accurate location of a photographic plate in each structure and in conjugate planes with respect to the lens, and two light sources on the sides of the planes remote from the lens. Thus plate carriers, Fig. 1 (not shown), having each a central window provided with three lugs for accurate location of a plate in the carrier and five frame-apertures for accurate location of the carrier itself in camera apparatus (Fig. 3) are located at h, o around lens z and the light sources are i, p. The apparatus has adjustment mechanisms of process camera type. Registration is automatic. When the original from which the uncorrected separation transparencies are made is itself a transparency the uncorrected records are preferably produced by placing the original in the carrier at o and effecting exposures at h with use of filters in the lens holder k. When the original is a flat copy the latter may be mounted on copy-board q (Fig. 4) which shows part of the apparatus with a replacement lens z<SP>1</SP> and mirror x to enable lateral reversal, exposures being effected at h as before. Specification 402,082 is referred to.

Abstract: 731,252. Dampers. LOEWENHEIM, E. Aug. 19, 1952 [Sept. 12, 1951], No. 21459/51. Class 51 (1). A swivel damper comprises an open frame member for installation in a flue and a damper member for co-operating with the frame member to close the passage therethrough except for a narrow space all round which is closed by strips of heat-resisting flexible sealing material formed at least in part of resilient material and each secured at one edge along an edge of one or other of said members so that the flat face of the strip on one side co-operates with the other member to form a gastight seal by virtue of the spring pressure of the resilient part when flexed. As shown, Fig. 1, a flue damper comprises blade 1, spring sealing elements 3, 4, and element abutments 5, 6. In a modification of this arrangement additional spring sealing elements are used instead of abutments 5, 6. In a gate type damper-plan views in Fig. 7-sealing strips 12 are secured to framework 11 whilst in a swivel balanced type the damper blade 1b has flexible elements 12 secured to it along all relevant sides in the Fig. 10 arrangement, but only to its upstream part in the Fig. 11 arrangement the other elements in this arrangement being secured to the frame 11b. The heat-resisting flexible and resilient sealing material may be used in the form of an elongated strip around the edge of the frame or damper or a plurality of strips placed in overlapping relationship may be employed. The resilient material may be in the form of strips secured in position in adjacent, spaced apart or overlapping relationship on one side or within a textile heat-resisting flexible material or on one side or within one or several layers of heat-resisting wire gauze. The woven sealing material shown in Fig. 18 comprises threads 26 of mineral fabric and wires 27 of heat-resisting resilient material. Specifications 565,714, 589,206 and 601,726 are referred to.

Abstract: 1302357 Protective arrangements TEXAS INSTRUMENTS Inc 5 May 1970 [29 May 1969] 21540/70 Heading H2K A protective arrangement comprises an A.C. semi-conductor switch means, e.g. triac 12 connected in series with a load 16 to an A.C. supply 10, a D.C. supply connected to the control element 14 of the triac 12, a unidisectional switch, e.g. a controller rectifier 20 or a transistor Fig. 2 (not shown), for shunting the D.C. from the control element 14, and sensing means 24 connected to the control element of the unidirectional switch. The means 24 may be one or more P.T.C. or N.T.C. thermistors responsive to the temperature, e.g. of a motor, or heated by a heater connected in the supply lines to a motor. In the arrangement shown, when a P.T.C. resistor 24 is sufficiently heated, the potential at a junction 56 is sufficient to cause a Zener diode 58 to break down so rendering a controlled rectifier 20 conductive. This shorts the D.C. supply provided by a rectifier 18 away from the gate 14 of the triac 12, so that the triac 12 ceases to conduct and the load 16 is de-energized. This load 16 may be a motor or a relay controlling the supply to machinery (not shown) and having holding contacts 34 is parallel with a "start" switch 30. Capacitors 62, 64, 66 render the arrangement insensitive to transient conditions . of the supply 10. Resetting is effected by a switch 36 though in an alternative arrangement, Fig. 2 (not shown), conduction is resumed automatically when the means 24 has cooled sufficiently. Reference is made to the use of a light sensitive resistor as the sensing means.
